Arsenic In Drinking Water And Public Opinion On Wildlife Management As Case Studies Illustrating Natural Resource Policy, Jessica Sargent-Michaud
Arsenic In Drinking Water And Public Opinion On Wildlife Management As Case Studies Illustrating Natural Resource Policy, Jessica Sargent-Michaud
Electronic Theses and Dissertations
There are various ways to approach policy planning. This thesis consists of two Maine natural resource issue case studies illustrating different approaches to policy analysis. The first, a case study of arsenic contamination, is an example of a study that assembles information and provides that information to the public to influence public behavior. The second, a case study of wildlife management, is an example of a study that surveys the public to collect information on the public's opinions and attitudes to influence agency behavior towards the public. Arsenic in drinking water in Maine is a public health concern. There may …
Effects Of Roadway-Related Physical And Chemical Habitat Alterations On Stream Ecosystems, Thomas Stuart Woodcock
Effects Of Roadway-Related Physical And Chemical Habitat Alterations On Stream Ecosystems, Thomas Stuart Woodcock
Electronic Theses and Dissertations
Roadways are an important feature of both rural and urban landscapes, and disturbances associated with them have a variety of effects on stream ecosystems. Organisms may be differentially affected by toxic substances, depending on such factors as sediment and water chemistry, toxin bioavailability, uptake and elimination processes, and tolerance mechanisms. The effects of heavy metal pollution and habitat alteration related to urbanization and industry were examined along a gradient of impact in Goosefare Brook, a small stream in southern Maine with a history of water quality impahlent. The structure of invertebrate assemblages changed significantly along the gradient, and were related …
Fire And Its Effects On Mercury And Methylmercury Dynamics For Two Watersheds In Acadia National Park, Maine, Kenneth B. Johnson
Fire And Its Effects On Mercury And Methylmercury Dynamics For Two Watersheds In Acadia National Park, Maine, Kenneth B. Johnson
Electronic Theses and Dissertations
Cross-continental movement of contaminated air masses and prevailing wind direction. Sites covered with softwood vegetation also received higher Hg deposition than other vegetation types because of the higher scavenging efficiency of the canopy structure. MeHg deposition was not affected by these factors. Hg deposition was lower in Cadillac Brook watershed (burned) than in Hadlock Brook watershed (unburned) because regeneration after the fire was dominated by mixed hardwood, whereas softwoods dominate the landscape in Hadlock Brook watershed. The lower deposition could also be a result of the watershed aspect; Cadillac Brook watershed faces southeast to east and Hadlock Brook watershed faces …
